A heat exchanger is provided to increase the size of the heat exchanger by arranging an inlet and an outlet in an air introducing direction of a header tank. A heat exchanger includes a plurality of tubes(10), upper and lower headers(30,30'), upper and lower tanks(40'), and upper and lower header tanks(60). A first baffle(45) is provided in first and second columns(41,42) to partition an internal space of the upper tank. A first communicating unit(51) includes an inlet pipe(43) and outlet pipe(44). The inlet pipe is provided at one side of the second column. The outlet pipe is used to discharge a refrigerant. The first communicating unit connects the first column with the second column on a rear separator(50) of the inlet pipe. A second baffle(47) is provided between the inlet pipe and the outlet pipe. A second communicating unit(48) connects the first column with the second column on the separator provided at the other side of the upper tank. |
